If you're wanting smaller form factor, Smok Alien or Smoant Battlestar are great mods.
The Hohm Tech Hohm Wrecher G2 has a great board with many capabilities including TC on kanthal.
There are a million mods on the market so without knowing more of what you want from a mod it'll be difficult to make solid suggestions.
As
Whiskey said, if you have tried some that you know you like, those may be the ones you want to look at.
Your eleaf100 was a fair mod.
They followed that with the TC100 that not only added TC mode (only fair rating) but also the fire bar, dual or single 18650 capability, smaller form, and very comfortable.
But many new devices have came out since with better technology.
